UNTTED STATES To all whom it may concern Be it known that I, THADDEUS O. HISTED, of Junction City, in the county of Davis and State of Kansas, have invented a new and useful Improvement in Hoisting Apparatus for Mining- Shafts, of which the following is a specification.

My invention consists in certain novel detailsof construction and arrangement of the Windlass, the tackle, and devices connected therewith, whereby provision is made for facilitating the operation of the apparatus, as hereinafter particularly described.

The invention is particularly intended for 1 use in mineral and other mines for hoisting the excavations from the mine-shafts; but it may be employed for various other purposes. It will here be described as used in connection with a mine.

In the accompanying drawings, Figure 1 is a side view, partly in section, showing the apparatus with the parts in position for raising or lowering the bucket. Fig. 2 is a side view, showing the bucket in the act of being tilted to empty its contents. Fig. 3 is an end View of the apparatus. Fig. 4 is a side view, hereinafter referred to. Fig. 5 is a sectional view of the drums Figs. 6 and 7 are detail views, hereinafter referred to.

Similar letters of reference indicate corresponding parts.

The various working parts of the apparatus are arranged and supported in a frame-work, A, which may be of any suitable construction. This frame may be secured to the ground by means of pins or stakes and it may also, if desired, be provided with a post, A for hitching a portion of the tackle, as shown.

In the lower part of the frame-work A, near 40 one end, is journaled a shaft, B, which carries the drum 0. This drum (see Fig. 5) is hollow, and is connected to the shaft by a clutch, so as to revolve therewith, but may be disconnected, so as to turn freely thereon. The clutch is of the construction shown in Fig. 6, and consists of two plates, D D provided with notches and ratchet teeth. Two of these clutches are employed in the drum.

At one end of the drum a plate, D, is at-" THADDEUS O. HISTED, OF JUNCTION CITY, KANSAS, ASSIGNOR OF ONE' HALF TO ANSON W. OALLEN, OF SAME PLACE.

HOISTING APPARATUS FOR MlNlNG-SHAFTS.

SPECIFICATION forming part of Letters Patent N0. 235,681, dated December 21, 1880. i

Application filed May 3,1880. (ModeL) tached to the inner side of the drum-head, and a plate, D is fixed to the shaft B. At the other end of the drum a plate, D, is attached to the outer side of the drum-head, and a plate, D is fixed to a gear-wheel, E, which, in turn, is fixed to the shaft B.

When the clutches are engaged the turning of the shaft B will cause the drum vO to turn, and when the clutches are disengaged the shaft may be turned without turning the drum.

For keeping the clutches engaged I employ a coiled sprin g, f, surrounding the shaft B, and having one end bearing against the clutchplate D on the shaft B, at the inner side of one end of the drum, and the other end hearing against the inner side of the drum-head at the opposite end of the drum, so as to have a tendency to keep the drum pressed towardthe right-hand side of Fig. 5. To assist in keeping the parts thus engaged I employ a shaft, G, journaled in the frame A above the drum, and provided with a wedge-shaped arm,

9, which may be inserted between the lefthand end of the drum and a gear-wheel, E fixed on the shaft B. At the opposite end of the shaft G from the arm 9 is a lever, 9 for raising and lowering said arm 9 when desired.

For disengaging the clutches when desired in order to allow the drum to turn freely to unwind the rope, I employ a lever, H, pivoted at one end to the frame A, and carrying near its other end a wedge-shaped arm, h, which may be inserted between the right-hand end of the drum and the inner side of the gearwheel E.

For retarding the speed of the drum when unwinding I employ a brake consisting of a lever, i, pivoted at one end and arranged so that it may be made to bear on the face of the drum.

Motion may be applied to the drum in any 0 suitable manner. As shown herein, the means employed consists of a shaft, J, journaled in the frame A above the drum, and provided with two pinions, jj meshing into the gearwheels E E. This shaft may be turned by hand-power by means of a crank, 9' It may also be provided with a pulley, 3' so as to receive motion through a belt from an engine; or

it may be provided with bevel-gearing so as to receive motion through a tumbling-shaft from a horse-power. The shaft J is provided with a ratchet, j", and pawl j", to prevent retrograde motion of the Windlass.

The hoisting-ropeused with this apparatus may be arranged in "arious ways in connection with pulleys, so as to employ two, three, or four strands for hoisting, according to the weight of the load to be raised.

As shown in Fig. 1, the rope K passes from the drum C upward and over two pulleys, l l, in a bar, L, suspended from one end ofa bar, M, on the top of the frame A, thence downward and under two pulleys, a a, in a carrier, N, from which the bucket O is suspended by a snap-hook, 0, thence over a pulley, p, at the lower end of arod or arm, P, carried by the other end of the bar M, and adjustable vertically therein by means of a nut, p thence around a pulley, Q, hooked to the post A thence back again and over a pulley, Q suspended from the bar M, and thence its end is attached to the carrier N by means of a hook, is, on the rope, and a link, M, on the carrier. Thus the weight and strain of the load are divided between three strands of the rope, and great power isobtained.

As shown in Figs. 2 and 4, the end of the rope is hooked to a staple or hook, 70 in the upper part of the frame A, and an intermediate pulley, Q is interposed between the pulley Q and the end of the rope, so as to produce four strands of rope, and thusstill greater power is obtained.

By dispensing with the pulley Q and attaching the end of the rope to the hook or staple k on the frame, the weightis sustained by two strands of rope, as shown in Fig. 3, and as will be understood on referring to Fig. 4.

The operation of hoisting the bucket is the same in all cases, whether two, three, or four strands of rope are used. The drum having been turned until the bucket is as high as it can be raised, and the rope Kis taut throughout its entire length, the portion of the rope between the pulleys l and the pulley Q is then perfectly straight and forms an inclined track,

' down which the carrier N runs with the bucket,

asshown in Fig. 2.

The apparatus is provided with a tilting device at the point where the contents of the bucket are to be emptied, which device consists of a frame, R, providedwith two hooks, r 1", said frame being adapted to be attached to the frame Aat any suitable point by means of a bolt. When the bucket O has been raised to its fullest height and is ready for the carrier N to run down the inclined track, a tiltingrope, R is hooked to a loop or staple, 0 on the outside of the bucket 0, near the bottom thereof. When the carrier N reaches the end of the track the tilting-rope R is pulled, so as to oscillate the bucket on the pivots of its bail and tip it over, so that its top edge on one side catches in the hooks r, and thus the contents of the bucket are discharged in the direction indicated by the arrows in Fig. 2. The carrier may then be run back on the track by pulling on the rope R The rod P is provided with afriction-roller, 1), just above its pulley p. This allows the portion of the rope K between the pulleys Q and Q to run freely when passing in contact with said roller. I

The rope K is provided with a loose washer, w, just above its hook it. When the rope is arranged in the manner shown in Fig. 1, as the bucket reaches its highest elevation and the ropeK becomes taut, the hook is is disengaged from the link a and the washer to prevents the rope from escaping through the pulley-block Q as illustrated in Fig. 7.

When the rope is arranged as shown in Figs. 2 and 4, the link g of the pulley-block Q is detached from the link a as the rope becomes taut, and said pulley-block Q, then assumes the position shown in Fig. 2.

The bar M, heretofore referred to, is attached to the top of the frame-work A by a bolt, m, so that it may be oscillated in a horizontal plane. The bolt m passes through one of the top rails of the frame, and the bar is provided with a friction-roller, m riding on one of the top rails at the opposite side of the frame.

A lever, S, is pivoted in a swivel-fulcrum on one of the upright posts of the frame A, and the upper end of said lever is connected by a rod, .9, with the bar M, by which means said bar is readily oscillated. WVhen the bucket O is in the act of being lowered or hoisted, the bar M is placed in a position nearly parallel with the direction of travel of the rope. When the bucket has reached its highest position, andwhile the carrier is running to and fro on the rope, the bar M is swung to one side, as shown in Fig. 3, so as to throw the rope off from the pulley 19 and allow the carrier N to clear the same and the rod P.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut- 1. The shaft G and wedge-shaped arm g, in combination with the drum 0 and gear-wheel E substantially as and for the purpose herein described. 4
